Representatives for Giancarlo Stanton, the reigning National League MVP, met with the Giants and Cardinals late in the week, as each team attempted to convince Stanton to waive his no-trade clause and pave the way for a blockbuster deal. The context behind those meetings became clearer on Sunday: Multiple sources said the Marlins have agreed upon the general framework of a Stanton trade with both San Francisco and St. Louis. Of course, those deals are on hold while Stanton considers whether he’d accept a deal to either team.
